We are beginning to completely restore and upgrade a pair of Silver-7 tube amplifiers.Something we haven't seen anyone else attempt before.

We'll be refinishing the chassis in high gloss black powder coating. The original lacquer finish was nice, but not durable what so ever. This new finish will last the life of the amplifiers. We will also be updating the RCA and binding connectors, and adding an IEC. also adding amber LEDs to the meters to match the Silver-1 preamp design.

A doctrine fostered by a delusional, illogical minority and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by the clean end.

In a recent press conference, President Obama remarked, "If I had a city, it would look just like Detroit."

Brian, nice work. I am curious tho, why all the different brands of caps?

Jessie.

Me not knowing the sonic difference, in in brands of caps I sent Chris Johnson @ partsconection (formally Sonic Frontiers)the wiring schematic to have a look at. The caps I used are what he chose, I did not question the the different brands, The ALEX are made by Duelund

Got it, thanks.

What I see are some bypass caps that were originally used to help out the crappy stock electrolytic and mylar caps. Since you are upgrading those, there really is no need to use bypass caps now. I've found that bypassing high quality film/foil caps results in unwanted artifacts. Also, not using bypass caps now will save you money.

One I don't really get is the OBLIG-74473 0.22uf (gold one), CLARITY-74839 0.25uf (silver one)and the ALEX-75267 0.01uf (black one, is that an ALEX) all together. Three different caps, three different flavors when all that is needed is one high quality 0.48uF cap.
